Aspergillosis is a fungal infection rarely observed in Cuba during the first years of the AIDS epidemic. However, the increase in aspergillosis cases diagnosed by autopsy in recent years, led us to study the epidemiological, clinical, radiological and anatomopathological characteristics of this disease among the Cuban AIDS patients. A total of 307 autopsies were reviewed, seven of them had invasive pulmonary aspergillosis (2.2%). The disease was predominant in men and in the white race. Neutropenia and drugs use were the risk factor more frequently observed. Clinical manifestations were those unspecific and common to other opportunistic infection of the respiratory system. The more common radiological picture were bilateral nodular infiltrates and cavitary lesions in the upper lobes (two cases). The anatomopathological diagnosis was based on the morphological characteristics of the agent and in the angioinvasive features of the pulmonary lesions. We suggest that aspergillosis should be considered in the differential diagnosis of opportunistic respiratory events of AIDS patients in advanced stages. 相似文献

目的 回顾性分析肺曲霉菌病的临床特征、影像学特点、手术治疗方式、随访资料,以期通过本研究提高对该病的认识水平,为制定更合理的临床治疗方案提供依据.方法 对丽水市中心医院心胸外科及呼吸内科2006年到2011年间确诊的50例肺曲霉菌病住院病例进行回顾性研究,按影像学特征及病理学特征分为27例慢性坏死性肺曲菌病(CNPA)和23例肺曲霉球(PA),并分析其临床及随访资料.结果 慢性坏死性肺曲菌病和肺曲霉球在性别,年龄,临床症状、基础疾病方面差异无统计学意义,都好发于陈旧性肺结核与支气管扩张患者.影像学上,CNPA和PA均可出现空气新月征,均好发于两肺上叶,但前者有胸膜增厚,空洞周围浸润阴影、厚壁空洞和洞壁不规则等特征.病理学上,CNPA和PA都可见锐角分支、有隔膜的曲霉菌丝,但前者有组织出血、坏死、微脓肿和炎性反应细胞浸润等特征.单因素分析后证实大咯血,体重减轻,是术后并发症危险因素.多因素通过COX风险比例回归分析证实年轻,无大咯血是生存预后有利因素.结论 组织病理学是鉴别慢性坏死性肺曲菌病(CNPA)和肺曲菌球(PA)金标准.空气新月征,是二者特征性CT表现,大咯血是术后生存独立的危险因素.手术切除完整的PA患者生存预后优于CNPA患者,提示对于CNPA患者术后需常规预防抗曲菌治疗. 相似文献

The model of experimental chronic pulmonary aspergillosis has been obtained in mice and guinea pigs by the intrapulmonary infection of the animals with the suspension of Aspergillus mycelium and spores in complete Freund's adjuvant. Such method of infection has made it possible to produce chronic local mycotic process. Morphologically, focal inflammatory changes of the lung tissue with the subsequent formation of a multitude of small abscesses in these areas have been observed as characteristic manifestations of aspergillosis. 相似文献

Cutaneous and pulmonary aspergillosis was diagnosed in rabbits. Dichotomous branching, septate hyphae typical of Aspergillus spp were observed in cystic hair follicles. Atypical, short, knobby mycelia with radiating projections were seen in nodular lesions in the lung. 相似文献

The role of intrinsic muscle flaps of the foot for bone coverage in foot and ankle defects in diabetic and nondiabetic patients 总被引:5,自引:0,他引:5

Local muscle flaps, pioneered by Ger in the late 1960s, were extensively used for foot and ankle reconstruction until the late 1970s when, with the evolution of microsurgery, microsurgical free flaps became the reconstructive method of choice. To assess whether the current underuse of local muscle flaps in foot and ankle surgery is justified, the authors identified from the Georgetown Limb Salvage Registry all patients who underwent foot and ankle reconstruction with local muscle flaps and microsurgical free flaps from 1990 through 1998. By protocol, flap coverage was the reconstructive choice for defects with exposed tendons, joints, or bone. Local muscle flaps were selected over free flaps if the defect was small (3 x 6 cm or less) and within reach of the local muscle flap. During the same time frame, the authors performed 45 free flaps (96 percent success rate) in the same areas when the defects were too large or out of reach of local muscle flaps. Thirty-two consecutive patients underwent local muscle flap reconstruction for 19 diabetic wounds and 13 traumatic wounds. All wounds, after debridement, had exposed bone at their base, with osteomyelitis being present in 52 percent of the diabetic wounds and in 70 percent of the nondiabetic wounds. Wounds were located in the hindfoot (47 percent), midfoot (44 percent), and ankle (9 percent). Vascular disease was more prevalent in the diabetic group, in which 42 percent of the affected limbs required revascularization procedures before reconstruction (versus 7 percent in the nondiabetic group). Subsequently, 83 total operations were required to heal the wounds, of which 46 percent were limited to debridement only. Thirty-four pedicled muscle flaps were used: 19 abductor digiti minimi (56 percent), nine abductor hallucis (26 percent), three extensor digitorum brevis (9 percent), two flexor digitorum brevis (6 percent), and one flexor digiti minimi (3 percent). An additional skin graft for complete coverage was required in 18 patients (53 percent). One patient died and one flap developed distal necrosis, for a 96 percent success rate. The complication rate was 26 percent and included patient death, dehiscence, and partial flap or split-thickness skin graft loss. Twenty-nine of the 32 wounds healed. One patient died in the postoperative period; in two others the wounds failed to heal and required below-knee amputations, for an overall limb salvage rate of 91 percent. Diabetes did not significantly affect healing and limb salvage rates. Diabetes, however, did affect healing times (twofold increase), length of stay (2.7 times as long), and long-term survival (63 percent survival in diabetic patients versus 100 percent in the trauma group). Local muscle flaps provide a simpler, less expensive, and successful alternative to microsurgical free flaps for foot and ankle defects that have exposed bone (with or without osteomyelitis), tendon, or joint at their base. Diabetes does not appear to adversely affect the effectiveness of these flaps. Local muscle flaps should remain on the forefront of possible reconstructive options when treating small foot and ankle wounds that have exposed bone, tendon, or joint. 相似文献

Secondary bone grafting of alveolar clefts has become a well-established procedure. However, little attention has been given to the soft-tissue coverage of these grafts. We present our experience with 32 patients in which gingival mucoperiosteal flaps were used exclusively in conjunction with bone grafting for patients with residual alveolar clefts. The indications and timing of the procedure as well as the steps of the technique are presented. The advantages of bone grafting at the stage of mixed dentition and the superiority of gingival mucoperiosteal flaps, including teeth eruption through the graft, additional teeth support, dental hygiene and aesthetic appearance of the alveolar ridge, are discussed. Our results are compared with those obtained with similar or other techniques. 相似文献
